Pen input for computing devices is now widespread, providing a promising interaction mechanism for many purposes. Nevertheless, the diverse nature of digital ink and varied application domains still present many challenges. First, the sampling rate and resolution of pen-based devices keep improving, making input data more costly to process and store. At the same time, existing applications typi...

Digital ink promises to combine the flexibility and aesthetics of handwriting and the ability to process, search and edit digital text. Character recognition converts handwritten text into a digital representation, albeit at the cost of losing personalized appearance due to the technical difficulties of separating the interwoven components of content and style. In this paper, we propose a novel...

This paper presents an interactive system for ink splattering, a form of abstract art that artists splat ink onto the canvas. The default input device of our system is a pressure-sensitive 2D stylus, the most common sketching tool for digital artists, and we propose two interaction mode: ink-flicking mode and ink-dripping mode, that are designed to be analogous to the artistic techniques of ink...

Two of the greatest obstacles to the implementation of the standardized electronic medical record are physician and staff acceptance and the development of a complete standardized medical vocabulary. Physicians have found the familiar desktop computer environment cumbersome in the examination room and the coding and hierarchic structure of existing vocabulary inadequate. The author recommends t...

While informal tools can benefit early design, their use requires that a designer surrender the richer affordances of physical tools. To better understand the importance of physical tools for early design, we conducted contextual interviews with twelve designers. We found that paper is an integral part of the early design process and argue that informal tools will not realize their full potenti...

A variety of different approaches have been used to add digital ink annotations to text-based documents. While the majority of research in this field has focused on annotation support for static documents, a small number of studies have investigated support for documents in which the underlying content is changed. Although the approaches used to annotate static documents have been relatively su...

The efficiency of ink separation in the process of waste paper recycling depends among other things on the ink properties, kind of the substrate, the printing techniques and the printing conditions. Chemical deinking flotation does not efficiently remove water based flexographic inks, UV ink and varnish, ElectroInk and some toners from digital printed paper. The use of enzymes could be an alter...

Ink completion is a technique for suggesting characters or words to users as they write with digital ink. With a simple gesture, users can accept a recommendation and continue writing. The technique improves the handwriting experience and is very suitable to support notetaking on tablet computers and PDAs.

Extracting characters from digital ink text is an essential step which leads to more reliable recognition of text and also a prerequisite for structured editing. Casualness and diversity of handwriting input result in unsatisfied accuracy of extracted characters. Reprocessing the initial extracted characters based on context makes some considerable improvement. Therefore, this paper proposes an...
